I disagree that the statement is useless, but here's some more info for you. I use China Telecom and China Mobile. Haven't tried China Unicom. ExpressVPN has a message on most of their apps saying to use Tokyo 1, HK 4 or 5, Los Angeles 5, or UK Wembley when in China. I have used all of those servers, although HK 4 and 5 are the fastest. I've used Shadowsocks and ShadowsocksR for my VPS. Switching ports will work for a while, but I've always found the server will get blocked eventually, possibly due to "active probing" as defined in this paper[1]. This person[2] suggests hosting a website from your Shadowsocks server as a cover, but I haven't tried it yet.
